Lacunarity and succolarity, two recently described fractal dimensions, were also computed. These parameters provided a precise description of porosity and pores’ characteristics. Non-linear relationships were found between several descriptors e.g. succolarity and star volume of

the material. A linear correlation was found between lacunarity and succolarity. These techniques appear suitable in the study of biomaterials usable as bone substitutes. (c) 2013 Elsevier B.V. All rights reserved.”
“We consider a channel state acquisition scheme in the cognitive radio (CR) ad hoc system. Unlike cellular CR systems, the channel state acquisition scheme, which uses a geolocation database, is hard to implement in an ad hoc CR system. Hence, we consider hybrid channel Pevonedistat state acquisition schemes that use cooperative multiband sensing

to build a virtual spectrum database for ad hoc CR systems, which we refer to as the spectrum pool. Then, we compare three schemes, i.e., a sensing scheme and two hybrid schemes, in which the spectrum information or the band can be cooperatively shared among CR users without using a dedicated common control channel. By using the spectrum pool, the CR users can have more information on the spectrum compared PCI-32765 cell line with the case when there is no channel state sharing. Therefore, the number of spectrum sensing attempts to find a vacant band that can be reduced, and the performance of CR systems can be improved. Through Small molecule library supplier simulation, we show that our analysis results are well matched to simulation results. We also find that the throughput can be improved by utilizing the spectrum pool.”
“The title compound, [(C(4)H(10)NSF(2))(2)][SiF(6)], was isolated as a decomposition product of diethylaminosulfur trifluoride. The structure consists of two monovalent (diethylamino) difluorosulfonium cations surrounding one divalent hexafluorosilicate anion. It crystallizes in the monoclinic space group C/2c with a = 13.7587(8) angstrom, b = 11.9160(7) angstrom, c = 11.6425(7)

angstrom, beta = 118.300(3)degrees, and V = 1680.63(17) angstrom(3). The structure contains an extensive hydrogen-bonding network as well as intermolecular sulfur-fluoride interactions. The compound was further characterized by (1)H-NMR and (19)F-NMR.”
“We introduce a non-invasive and accurate method to assess tibialis anterior muscle temperature (Tm) during rest, cycling exercise, and post-exercise recovery using the insulation disk (INDISK) technique. Twenty-six healthy males (23.6 +/- 6.2 years; 24.1 +/- 3.1 body mass index) were randomly allocated into the ‘model’ (n = 16) and the ‘validation’ (n = 10) groups. Participants underwent 20 min supine rest, 20 min cycling exercise at 60% of age-predicted maximum heart rate, and 20 min supine post-exercise recovery. In the model group, Tm (34.55 +/- 1.
